Agenda

• Capability / RequiredCapability and Query
• Status update on higher level of repo (colocated, referenced, etc.)

Minutes

Query

• Ian to remove the Collector from the IQuery this week. This will be a large change. Ian wants to have everybody released to avoid merging pain for others.
• Thomas has added a new patch and created the new project to have the new support for the query language.
• Andrew to move IQueryable interface up the hierarchy on IRepo and IRepoMgr

Metadata

• Pascal and DJ explore the addition of typing to ProvidedCapability and RequiredCapability. There are 3 possibilites:
  • Comparable (and the requirement expression become more like a filter),
  • a new type like p2Value and a corresponding type describing interval of values (this allows for complex logic in comparison and inclusion check)
  • Properties, everything on the capability becomes an entry in a map (namespace, name, version) and things are mapped against it using a ldap filter style expression.

• There is also a discussion to be had about the relationship between a query and requiredcapability

It seems that at this point we can not commit in making IRequiredCapability / IProvidedCapability API. This may not be an issue since this data is only targetted at the planner and some queries that we can provide out of the box.

Engine

• Simon to Release of the Touchpoint / Action and Memento in their final package
• Discussion on how to return results from Phases? We have a problem today with the Sizing PhaseSet
• Discussion on how to try to get rid of operands from the API
• Actions are not properly initialized against the proper instance of the Agent

Director / repo

• Work on a API to keep track of the relationship between repos in order to simplify ProvisioningContext.
